  In the present study, reaction kinetics was carried out using low grade calcareous phosphate rock particles in dilute phosphoric solution. To study the reaction parameters a number of experiments were carried out in a glass reactor column. The results indicate that the selective leaching of the calcareous material in the rock is controlled by the fluid layer depending on the reaction conditions. The results also show that the value of reaction rate constant does not appear to be a strong function of the particle size while the value of mass transfer coefficient increases with an increase in particle size.
